Wide-Vue Analog Panel Meters Ordering Information Percent Motor Load Meters Model / Size and Catalog No. Rating DC load meters require an external shunt and potentiometer (not supplied). Use 8 to 10Ω, 2 watt wire-wound potentiometer. The appropriate shunt should be selected from accessory section and ordered separately. To select the proper shunt, first obtain the full load current rating of your motor from the name plate, manufacturer’s specifications of N.E.C. listing. Multiply that rating by 1.25 and select and order the shunt with an amps rating as large or slightly larger than the calculated...
